TO ALL WH'OM IT MAY CONCERN:

Be it known that I, O. T. GLEASON, of Farmington, in the ourityofFranklin, and State of Mai ne,`have inventedv a new and improvedVelocipede; andI do hereby declare that the following is a full, clear,and exact description thereof, lwhich will enable those skilled inthe:art to make and use the same, reference being had to the accompanyingdrawings, forming part of this specification, in which-- Figure l is asectional elevation of my improved velocipede, the section being takenthrough the line :r z of ii 2.

y 'igure 2 is a detail view. ofv one kwheel and the crank from asector,through the'line y y, iig. 1.

Similar letters of reference indicate corresponding par-ts.

The object of this invention is to obtain locomotion' by the directapplication of the weight of the operator to the crank of' thedriving-shaft, together with other devices, which will hereinafter befully set forth.

In the accompanying plate of drawings, the frame or platform of themachine is shown at D.

. The running-wheels are provided with interior friction-bosses orwheels A, which are in contact with the driving-wheels P, as shown.

'Ihe driving-wheels are at the extremity of a. sh'aft,-J, which latterisbent to form a double crank, I, as shown,

The shaft of the driving-wheels has its bearings in levers-L, whicharcjpivoted to stud-pins d, projecting from the uprights o, which latterarise from the platform D.

The opposite ends' ofthe leversLare connected with rods N, the frictionof which will be afterwards shown.

The treadles H are hung on the cranks, as shown, and' the operator,stead-ying himselfl by the cross-piece M of the uprights O,prop els themachineby revolving the shaft J'. 'A i The faces of the bosses A and ofthe drive-wheel P are covered with any Toughened material, as roughenedleather, to insure their eifective operation.

An endless track, composed of the hinged parts C CVC, as shown, looselyclose each of the two wheels on a side, and are kept in proper positionby means of the flanges B of the' rolling wheels as shown.

By this -mans the track is laid in front of the wheels, and passes overfrom the rear of the same in an vendless belt, as shown'.'

The guide-rails G are supported above the traction-wheels, by means ofvarms e, as shown, and prevent the t jointed track from leaving theanges.

The levers E having 'coge a a a, are hinged at g to -a cross-piece, z',supported from thefplatform D by 'arms 7L, projecting from the platform,as shown. l v

There are two ofV these levers, one at eachside of the platform, andtheir function is to alter the direction of thc vlocipede, bybeing'thrust down by the rods N., which latter pass upwardthrough thecrossfpiece M, and are manipulated by the person actuating the machine.v 'f The rods N being also connected with the bearing-levers L, thedriving-wheel -P-of the same side is lifted from contact with the bossesA Aof the traction-wheels, whereby the machine turns readily upon thestill wheels, as will be obvious. I

When aA level pavement is available, orY the ordinary road is ofsuiiici'ent evenness, the jointed track may be dispensed with, 'and thetraction-wheels used directly upon the ground o'r pavement. y

In this case the -flanges B being disks of sheet metal, attached bymeans ofbolts to the traction-wheels, are readily removed.. l

I claim as new, and desire to secure by Letters Patent--` l. Thecombination of four traction-wheels, each having a friction-boss, A,with the friction driving-wheels P, shaft J, double crank I I,andtreadles H H, allsuhstantially as shown and described, and for thepurpose set forth.

2. The lcvenbearings L, rods N, and steering-,levers E, all constructedand operating together, substantially as shown and described, and forthe purpose set forth.
